The book opens with a Nebraska farmer rushing to the hospital to see his youngest son, who was severely injured in a car accident, and from whom he has been estranged for some time. When he arrives, he finds Buddy in a coma. But the two men discover a mental connection that allows Buddy and his dog from childhood to take the father on a trip down Memory Lane. During that week, we learn the reason for the estrangement (it's not a spoiler to tell you that Buddy is gay), and Dad has the opportunity to rethink some things -- and maybe even come to a greater understanding about his own life.

I've been a big fan of Leland Dirks's writing since I read Jimmy Mender and His Miracle Dog, and I've read several more of his books since then. This one felt a little rushed to me. A great deal of the book is, of necessity, dialogue, and of course it's not taking place in a physical space, so some of the things an author might use to help with pacing aren't plausible -- body language, for example. Still, I wished for a momentary pause now and then.

But that's a minor quibble. Dirks handles a difficult topic with his usual stellar sensitivity. And I learned a few things about rainbows along the way. Recommended.
